Intermittency and turbulence in a magnetically confined fusion plasma

V. Carbone, L. Sorriso-Valvo, E. Martines, V. Antoni, P. Veltri

摘要:

本文研究了反向场箍缩等离子体中磁湍流的不稳定性。我们表明,磁场差异的概率分布函数不是尺度不变的,这是这些功能的翅膀更重要的是在最小的尺度,一个经典的签名的不稳定性。我们发现,标度律也出现在一个区域非常接近的限制设备的外壁,我们提出的证据表明,所观察到的不透明度增加移动到墙上。

英文摘要:

We investigate the intermittency of magnetic turbulence as measured in Reversed Field Pinch plasmas. We show that the Probability Distribution Functions of magnetic field differences are not scale invariant, that is the wings of these functions are more important at the smallest scales, a classical signature of intermittency. We show that scaling laws appear also in a region very close to the external wall of the confinement device, and we present evidences that the observed intermittency increases moving towards the wall.
